ADA and ICC A117.1: Elevator Accessibility in the United States

In the United States, elevator accessibility is governed primarily by the ADA Standards for Accessible Design and the ICC A117.1 standard, alongside ASME A17.1. They set car dimensions, control reach ranges, signage, and audible/visual signalling.

What the rules require

Requirements include minimum car dimensions and door clear width, control button heights and Braille/tactile markings, audible and visual car-position and hall signals, and door reopening protection. ICC A117.1 provides the technical criteria referenced by the building code and ADA.

Impact on modernization

Accessibility-driven modernization commonly includes new car operating panels and hall fixtures at compliant heights, tactile and Braille markings, gongs and lanterns, and voice annunciation — frequent scope in public and commercial upgrades.

How Vertisk helps

Vertisk maps accessibility scope from US tenders to compliant fixtures and signalling so bids reflect real ADA/A117.1 requirements.

Frequently asked questions

Do ADA requirements apply to modernization?

Alterations to elevators generally must comply with the applicable accessibility requirements to the maximum extent feasible; the local building code and adopted A117.1 edition govern specifics.
